MTN'S VERY TIRED (BUT NEW) CUSTOMER

I do not know how many times I have to complain when it comes to MTN. Firstly, I was debited TWICE. Secondly, I CANNOT USE MY WIFI SINCE IT DOES NOT CONNECT. Thirdly when I try and call mtn all I get is "Hello, welcome to MTN. My name is xyz, how may I help you?" the the call ends. I thought it was my network, so I called again. This happened 3 times already. But how am I supposed to get helped if I cannot even speak to MTN's consultants? My contract with MTN is new. Last month was supposed to be the first time I get debited which resulted in me getting debited TWICE. It's very sad how I, as a customer buys a product from MTN but I have to struggle so much with your service. Very sad also that canceling this contract would result in me paying A LOT of money. I swear its as if this is done on purpose.
